PATENT 4 NAIL DISTRIBUTING AND DRIVING MACHINE.

QPECIPICATION forming part of Letters Patent No. 356,209, dated January18, 1887.

Application filed October 8, 1886.

To all whom, it may concern:

Be it known that I, FREEBORN F. RAYMOND, 2d, of Newton, in the county ofMiddlesex and State of lrlassachusetts, a citizen of the United States,have invented a new and useful Improvement in Nail Distributing andDriving Machines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification, in explaining its nature.

The invention is an improvement upon that described in the Towns andRaymond Patent No. 346,137, and in my application filed August 28, 1886,Serial No. 212,040; and it re-' lates, essentially, to the arrangementand com-- bination, in an organized machine, of an apparatus ormechanism for supplying fastenings through a stationary throat orpassage, a movable distributer having a number of holes or passages forreceiving and guiding the nails or fastenings to a carrier or directlyto the naildriving devices, which is provided, preferably, with anintermittent movementin relation to said throat to bring its receivingholes or passages successively in line therewith, and with a continuedreturn movement to bring the dischargeoutlets of its holes or passagesinto a relation to the nail-carrier or to the nail-driving devices forthe delivery of nails or fastenings thereto. 7

It further relates to the arrangement and combination, in an organizedmachine, of the fastening, feeding, or supplying device hav- Fig. 1.

ing a stationary throat or passage, the movable distributer' having themovements indicated, and nail-driving devices arranged to drive thenails or fastenings as a gang or group.

It further relates to various details of construction, as willhereinafter appear.

In the drawings, Figure 1 is a view in rear elevation of the upper partof the machine containing the features of my invention. Fig. 2 is a sideelevation thereof. Fig. 3 is a vertical section upon the line at a: ofFig. 1. Fig. 4 is a horizontal section upon the line y y of Fig. 1. Fig.5 isahorizontal section upon the line a a of Fig. 1. Figs. 6, 7, and 8show a slight modification of the construction hereinafter referred to.Fig. 9 is a detail view in rear elevation .to illustrate various partsin a different position from that represented in Fig. 10 is aperspective view with a part of the nail-distributor attached. Fig. 11

Serial No. 215,657. (No model.)

is a View principally in plan, enlarged to rep- .resent the nail-stripfeed and detent-pawls.

for this purpose a device adapted to sever nails from a comb-strip, andto deliver them through the stationary throat in succession. Itcomprises a feeding device for feeding the combstrip with anintermittent feed, a detent for holding or looking the strip stationaryafter it has been fed and during the return movement of the feed, and aplunger or punch which is reciprocated to sever nails in succession fromthe end of the strip and move. them downward through the throat to thenail-distributer.

a represents the feed-pawl of this device. It may be reciprocatedby'acam, as described in my said application, or as hereinafter described.

a is the detent, which is in every like that of my said application.

a is theplunger or punch, and a the throat, and they are like theplunger and throat of the fastening making or severing device of my saidapplication, with the exception that the throat is stationary. Theplunger is reciprocated by the cam b 011 the shaft B.

The distributer which I have represented is adapted to supply nails orfastenings to a movable nail carrier or receiver, which receives them inthe form of a group and advances them in that form to group-nailingdevices. The distributer should have passages or holes arranged in astraight line at their upper ends, and brought into any desiredarrangement for the delivery of fastenings. at their lower end; and asthe machine which I haveshown in the drawings is organizedforheel-nailing,the distributeris shown as arranged to deliver agang orgroup of fastenings adapted to attach a heel-blank. It is probably bestformed by a block, O,having the straight line of holes 0 arrangedtherein at a uniform distance from each other, and a block, 0, havingholes 0 arranged in alinein which it is desired to drive the nails.

respect This block a is below the block 0, and the holes a are connectedwith the holes '0 by means of passages formed by the tubes 0. This block0 has a sliding hole-covering plate, 0 which is closed and held closedby aspring, and is opened upon the movementof the nailearrier D bycontact of a pin thereon with the edge of the plate when the carrier hasbeen moved so as to bring its nail-receiving holes in line with theholes of the block 0.

The distribnter is mounted in or upon the traveling support or carriageE, shaped in plan substantially as shown in Fig. 5, having the space 0for the reception of the block (1' of the distributer, and also asupport or ledge, 6, about the opening 0, upon which the flange of theblock 0 rests. The distributor is held in place in this recess by theswinging latchbar 0". The support or carriage E also has the extension6', and it is supported upon the bed or table F, which has guidesf andcap-plates f, which project upon the upper surface of the carriage E.

The distributer-support E is given an intermittent feeding movement tobring the holes a in successive order in line with thestationary throatto, and to provide it with this movement I have arranged upon thesection or arm 6* of the carriage Ea rack, G, which is attached to thearm a by screws, or in any other desired way, and I have arranged abovethe rack, to engage therewith,a worm, g,whiehis mounted upon the shaft9. This worm has a thread so shaped that upon engagement with the toothof the rack it advances the support or carriage E duringa part of therotation of the shaft 9, and holds it stationary during the remainder ofsaid rotation. This worm is well represented in Fi s. 1 and It isoperated by the bevelgear 9'" at its end and the bevel-gear g at thelower end of the vertical shaft 9', which shaft is connected with theshaft B by the bevel-gear /y The worm-shaft g is supported by asupportor arm, 9 adapted to permit the upward movement of the end of theworm-shaft g and disengage the worm g from the rack. There is secured tothe arm 1 a block, g which has an inclined or cut-away surface, g".There is arranged upon the arm 9 an adjustable tripping-block, H, whichis in substance like that describedin the Towns and Raymond patent referred to, and it governs the number of nails delivered to thedistributor. It is adapted to be moved and secured in any desiredposition upon the arm a or the rack-bar, and its upper surface isarranged to come in contact with the under surface of the block y, tolift the worm from engagement with the teeth of the rack when it isdesired to stop the delivery of nails to the distributer.

In order that the carriage B may be immediately returned to its originalposition upon the disengagement of the worm from the rack,

, which of course will withdraw the support H from the block g it isnecessary to bring into operation a device for holding the worm fromcontact with the rack during this return movement of the carriage, andthis I have represented in the form of a notched arm, M, extendingupward from the swinging support or arm 9 and which has the twoshoulders at m, one above and back of the other. There is arranged abovethis notched arm M a lever, 122 which is pivoted at m", and has thedownward-bent end in, (see Fig. 1,) which is adapted to rest upontheshoulder on when the worm. is in contact with a tooth of the rack,and upon the shoulder m when the worm and its swinging arm 9 have beenlifted by the block H. This gives the latch-lever m3 two positions, andenables it to be used in operating the shipping lever P, as hereinafterdescribed. It is moved automatically to release the arm M by means of acam on the shaft of the heel-nailing machine (not shown) and aconnecting-rod, m. The organization is such that the cam gives thelatch-bar an upward movement to release the notched arm, and thereforethe worm, which then drops into place to engage with the teeth of therack-bar.

I do not confine myself to the especial mechanism for moving thedistributer forward with an intermittent movement, as I may employ anyequivalent for the worm and rack. I would further say that thedistributer may be arranged in relation to the carrier so as to deliverits nails thereto upon the end of its forward movement, instead of atthe end of its reverse movement.

The position of the latch-bar shipping-lever and worm and its supportwhen the machine is in operation is shown in Fig. 1, and when themachine is stopped or the worm lifted to permit the movement of thedistributor, as shown in Fig. 9, of course the worm is held fromengagement with the rack during the backward movement of the distributorand its carriage or support E to a position to deliver fastenings to thenail-carrier. Any suitable means may be employed for giving the carriageor support this motion, and I have represented the weight n, attached tothe rack by a cord passing over the pulley n, connecting the worm c withthe weight, for accomplishing this purpose. The upward movement of theworm-shaft to disengage the worm also causes the end of theshipping-lever 1 to fall into a position to be moved horizontally by thelever 12, operated by the cam p This pushes the driving member 12 of theclutch from the driven member, and also causes a friction-brake (notshown) to bear against the driven member of the clutch, and the machineimmediately comes to rest.

To start the machine it is simply necessary to raise the end of theshipping-lever P from engagement with the latch-lever 1;,as this permitsthe spring f to draw the driving member of the clutch into contact withthe driven member of the clutch, and this is accomplished by means ofthe push-rod p", which is connected with the latch-lever.

The distributor is applicable to any fHSfGII' ing forming or separatingmachine adapted to deliver fastenings through two or more throatssimultaneously or successively without essential difference in theorganization of the dis tributer. The difference in its operation whenso used is that it is moved a greater distance by its feeding mechanismto move the holes receiving nails out of register with the throat andnew or other holes into register therewith.

For the purposes of this invention it is not essential that thenail-distributer include the nail-holder, as the tools may be arrangedto deliver nails or fastenings directly to the naildriving devices or tothe nail-carrier. Still, for ordinary purposes it is preferable that thetubes be brought together at their lower ends and held by someconnection which shall be an equivalent of the nail-holder and block,and it is also desirable that the two shall be connected at their upperends by a plate or block. The cam p may be used through the lever 19 foroperating the support or slide for the feed-pawl a, the support beingconnected with the end of the lever by means of a link, P. Thisconstruction is represented in the drawings.

The distributer, instead of being secured to the carriage or support E,as above described, may be fastened or bolted to the end thereof bymeans of the two rods I P, which arefast to the ends of the carriage-andare adapted to enter holes in the block 0 of the distributer, and nuts.This construction is shown in Figs. 2, 3, and 5 of the drawings.

In use, upon the release of the driving mem ber of the clutch it isdrawn into contact with the driven member. Simultaneously with thismovement the wormshaft for drivingtthe distributer is released and theworm engages the rack on the carriage E. The nail-strip feeding andsevering mechanism immediately begins to operate, and nails are severedfrom the end of the comb-strip in successive order and delivered throughthe throat of the machine through the holes of the distributer as it isintermittingly moved forward to bring them in register therewith insuccessiveorder. This portion of the mechanism continues its operationuntil a sufficient number of fastenings have been delivered to thedistributer, when the block determining the number of fastenings to bedelivered comes in contact with the projection connected with theworm-shaft, lifts the wornrsliaft, disengages the worm from the rack,brings the worm-shaft-holding latch into position to hold the shaftandworm elevated, and causes a connection between the cam and thedriving member of the clutch, whereby it is unshipped anda brakeapplied, and brings into operation the weight for returning thedistributer to its original position. The nailcarrier is then movedbeneath the distributer, if not alreadyin that position, and the slidingholecovering plate moved and agang or group of fastenings delivered tothe carrier. The carrier then moves forward sufficientl y to permit thesliding plate to close the holes of the distributer, and thenail feedingand distributing devices are automatically set in operation to makeanother load of nails. Meanwhile the carrier ismoved todeliver its loadof nails to the nail-driving devices.

The movement of the distributer is intermittent while receivingi'astenings from the throat a and is conti nuous during the reversemovement. The weight serves to keep the teeth of the rack in contactwith the edge of the arm, so that there is no backlash and the holes ofthe distributer are always brought into active register with the throat.

The worm is shaped to perform two functions: first, it moves thedistributer the distance between the centers of two holes in the block0, and after thus moving it into the holes the block is locked in thatposition while the nail or fastening is being delivered to a holetherein from the throat. The arm of course does not stop its rotation,and the effect is produced entirely by the shape of the thread of theworm.

I may use, in lieu of the worm and rack feed, a ratchet-bar or any otherequivalent device ..for providing the distributer with this intermittentmovement.

The movementof the distributer may be the reverse of that aboveindicatedthat is, it may be continuous on its outward movement andintermittent upon its returnin which case it would receive thefastenings from the throat upon the return movement and would deliverthem to the nail-carrier and nail-driving devices and then return to itsoriginal position, to again be moved forward.

The nail-carrier and nail-driving devices are similar to those describedin various of my patents.

I am aware that in Patent No. 346,137 and in Patent No. 347,960 there isdescribed a nail making and distributing machine having stationarynail-making devices, a stationary distributer, and an intermediatemovable nailreceiving block, which receives the nails from thenail-making machine or devices and de-' livers them to thestationary-distributer,while in the invention herein described Idispense entirely with the intermediate movable block above referred to,and use a movable distributer instead of a stationary distributer; and Iwould say thatI do not claim herein anything shown and described in saidpatents.
